(Cl. 197-9) sation taking place among several persons, theseries of signs corresponding to the words expressed by each personjoining in the conversation must be differentiated from the others.

It is the chief object of this invention to provide a machine of thetype broadly defined hereinabove wherein one or a plurality of memberscan be engaged in or disengaged from their operative position by theoperator, at will, these members when operative causing identifyingmarks to appear on predetermined portions of the paper tape.

This invention is also concerned with a novel industrial productconsisting of a paper-tape roll carrying on its side edges identifyingmarks visible when the tape is wound in roll form, so that the positionor relative location of the corresponding passages or groups of signscan be found immediately.

According to a first form of embodiment of the invention, a device isprovided having control means whereby the operator may cause a pointedmember utilizing a suitable color ink or any other means of this kind tocontact the paper tape of a machine of the'type indicated so as to printa line thereon as the tape is reeled ofi from a feed roll or spool; byproviding a plurality of difierently colored points the operator is ableto mark for identifying purposes. as many passages or groups of signs asthere are combinations available between these points.

According to another form of embodiment of this invention, the machineis provided with complementary or additional type-levers adapted whenreleased through suitable control means to be engaged in or disengagedfrom their operative position, and the universal bar (or equivalentmember of the machine which is positively driven upon each keyactuation) will automatically cause these type levers to print the typecarried thereby on the paper tape when. they are in their operativeposition, each time the operator depresses any key in the machine.

The attached drawings forming part of this specification illustratediagrammatically by way of example one form of embodiment of theinvention. In the drawings:

Referring-firstto. Fig l of: the drawings the: section oft papen'tape:shown therein carriesrcharactersr onsigps 2; corresponding-.101 therecordingof; a. text. by ashorthand typewriten;

In the uppermost portion 3 of thQxSQCtiQIl; identifying marks 4 areprinted along the right handaedge; of; the

tape; in the nextpertion. 5: of. thetape, similar marks 6 are printedonthe leftvhand edge; in the following portion- -,7, identifying marks-.4and.6 -have. be.en-printed simultaneons-ly' on eaohtside of thetape,,a-nd.finally, thezlqwer.- most portion 8 of the section carries noidentifying marks at all.

It will be readily seen that, by using only two marking devices, fourcombinations, for example those corresponding to the tape sections 3, 5,7 and 8, can be obtained; moreover, these marks are visible on the edgeof the paper tape in roll form, so that any desired portion of thedifferent groups of signs recorded thereon can be located at a glance.

This paper-tape marking may be obtained by utilizing a shorthandtypewriter of the type shown in Fig. 2 equipped with the mechanism to bedescribed hereafter with reference to the other figures of the drawings.

This machine is of the conventional type and therefore most of its knowncomponents are not shown in order to simplify the drawings; however, andaccording to this invention, it includes on its right-hand and lefthandsides additional type-levers 9, 10 and actuator keys 11, 12 therefor,each key being adapted, through a singleloaded sheathed flexible cable13, to rotate step by step a six-toothed ratchet wheel 14; a leaf spring15, by engaging the teeth 17 of the ratchet 14, prevents the latter fromrotating in the clockwise direction (Figs. 3 to 6) and urges resilientlythe ratchet 14 into one of the six positions provided by these teetch17; a cam member 16 retatably fast and coaxial with the ratchet 14 isformed with three projections 18 and three notches 19 cooperating with afollower 20 fast with the additional type-lever 9, 10 and constantlyurged by a suitable spring 21 against the cam member 16.

, The follower 20 engages a notch formed for this purpose in theuniversal bar 26, the edges of this notch being shaped to act throughits portion 22 as a cam adapted positively to prevent the correspondingtype-lever from rocking abouts its fulcrum pin 23.

When the toothed wheel 14 and cam member 16 are in such angularrelationship to each other that one of the projections 18 of the cammember registers with the follower 20 of the type-lever, and theuniversal bar 26 is rocked to the position shown in Fig. 7, the relevantprojection 18 will positively prevent the type-lever from pivoting aboutits fulcrum 23 and the type-lever will be held back.

However, if on the one hand the angular relationship between the toothedwheel 14 and cam member 16 is such that a notch 19 of the latterregisters with the follower 20 of the type-lever and on the other handthe universal bar 26 is pivoted, the spring 21 will swing the type-lever(Fig. 8), and the portion 24 of the notch formed in the universal bar26, which also acts as a cam member, will rotate the type-lever 9 in theclockwise direction so that the type 25 carried thereby will strike theimpression roller 27 and print a mark on the edge of the paper tape.

It will be readily understood that with a device of the type describedhereinabove, it will be suflicient to depress the keys 11 and/or 12 forsetting the marking mechanism in operative or inoperative position andthat after this mechanism has been set in its operative position themarks will be printed automatically until the mechanism is restored toits inoperative position by depressing again the relevant key, andvice-versa.

Of course, the form of embodiment described hereinabove is merelyillustrative of the manner in which the invention may be carried out inpractice, and many modifications may be brought thereto withoutdeparting from the spirit and scope of the invention. Thus, notably, thetiming of the machine may be facilitated by forming the cam portions 22and 24 as detachable or insert members adapted to be adjustably mountedon the universal bar of the machine.

What I claim is:

1. A machine of the shorthand typewriter, calculating and like typeadapted through keys and type levers to print signs or characters on apaper tape fed longitudinally, said machine having a universal baractuated by said keys and comprising at least one additional typeleveradapted to print a particular sign on a given portion of the paper tape,and means for putting said typelever in its operative condition, thesaid universal bar comprising a portion acting as a cam adapted tocontrol the actuation of said additional type-lever when it is in itsoperative condition, each time said universal bar is swung consequentupon a depression of a key in such a manner that said additionaltype-lever prints said particular sign on the paper tape, in addition tothe type controlled by the depressed key.

2. A machine according to claim 1, in which the means for putting theadditional type-lever in its operative condition comprise a cam havingat least two positions, one in which said type-lever is released andanother in which said type-lever is withdrawn from the action of saiduniversal bar.
